A little while ago, Madfinger Games pushed a pretty major update to its new zombie-filled apocalyptic first-person shooter Dead Trigger. This update brought new weapons, arenas, levels, and zombies; it also brought an unexpected perk: a new price of free.

Now you can get in on all of the action without paying a dime. Of course, if you still want to show the developers some love (which I highly recommend), you can also do so through the in-app purchasing system.
